As of August 18, 2019, there have been 7 confirmed cases of Listeria monocytogenes linked to Rosemount brand cooked diced chicken in British Columbia (1), Manitoba (1) and Ontario (5). Individuals became sick between November 2017 and June 2019. Six individuals have been hospitalized. Individuals who became ill are between 51 and 97 years of age. The majority of cases (86%) are female.

The collaborative outbreak investigation was initiated because of an increase of Listeria illnesses that were reported in June 2019. Through the use of whole genome sequencing, two Listeria illnesses from November 2017 were identified to have the same genetic strain as the illnesses that occurred between April and June 2019.

It is possible that more recent illnesses may be reported in the outbreak because of the delay between when a person becomes ill and when the illness is reported to public health officials. In national Listeria monocytogenes outbreak investigations, the case reporting delay is usually between 4 and 6 weeks.
